TKO 600, cant get into 3rd?

[Bundmar]

Ive had problems getting into 3rd gear from day one.
Only at high RPM's it wont go into 3rd seems like something is blocking it from getting into 3rd, it happens alot...anyone know if there is a fix for this, ive read other ppl having the same problem.

I just put a tko 600 in my car with a spec stage 3, and a steeda tri-ax, ram steelflywheel and i am have noticed the same thing which i know its got to be broke in but i still dont think it should be acting that way, i thought it was all cool in buying this trans but its really making me regret it hearing all of these complaints and i just spent an @$$ load of money to get all the stuff to put it in

Ive had my TKO600 in for over a year and had the same problems with it. I am doing an engine swap at the moment and while the motor was out I sent the tranny back to D&D for repair since I bought it from them.. basically 2 things were done.. something was out of spec with the gear lash on the mainshaft and they also removed some of the teeth on the 3rd gear syncro to cure this problem.. my car will be back up running in another week or so and I will report in on how the tranny is now so you guys know a possible route to fix it.

Just installed my tko 600 from d & d about 2 weeks ago. My shifts threw every gear at redline like a hot knife through butter. I would send it back if i was you. I use GM synchromesh
